Objective
Demonstrate and analyze the Doppler effect using sound waves.
Materials
- Tuning fork or sound source
- Microphone or sound sensor
- Timer
- Notebook for recording data
Instructions
- Generate a constant sound using a tuning fork or another sound source.
- Move the sound source toward and then away from the microphone or sound sensor at a constant speed.
- Record the frequency of the sound as detected by the microphone.
- Repeat the experiment at different speeds and distances.
- Analyze the changes in frequency to understand the Doppler effect.
- Present your findings in a report, explaining the Doppler effect and its applications in various fields.
